Our 94 Trooper is flipping out...check trans light coming on, etc...recalled
that being caused by a faulty alternator. Did some digging in the archives,
sure enough it is. Since then I've noticed it several times jumping up
close to 16v on the gauge (and all lights getting very bright at night).
So...it's waiting to go to the shop for an alternator.
The other problem that has cropped up since this started, and I'm not sure
if it's related or a coincidence, is that the hi-beam headlights won't work.
Lo-beam is fine, but when you switch to high, they just turn off. Marker
and cornering lights stay on just fine. I checked fuses and swapped around
the only possibly suspect-looking relay, but no go. Any thoughts?
